下面这样的代码就会超时：
__int64 getvalue (int n)
{
	int i,c,l;
	__int64 ans;
	l = 0;	
	for (i = 2; i < sqrt (n) + 1; i++)
	{
		c = 0;
		while (n % i == 0)
		{
			n /= i;
			c++;
		}
		if (c != 0)
			f[l++] = c;
	}
	len = l;
	ans = 1;
	for (i = 0; i < len; i++)
	{
		ans *= ((f[i] + 1) * (f[i] + 2)) * ((f[i] + 1) * (f[i] + 2));
	}
	ans >>= (len + len);
	return ans;
}
